在中包浇注之前,需按升温曲线对中间包烘烤至1150℃。传统的中间包烘烤装置有自动点火、火焰监视、煤气管路检测、氮气吹扫功能,需用热电偶测温,材料损耗大,成本增高,大约每只电偶只能用一周左右。如果在满足工艺要求下,在中包烘烤过程中,不进行时时测温,而采用流程化的烘烤,将节约大量成本。根据风量与煤气量的特性曲线,在不考虑其它因素的情况下,可不用升温曲线而直接用风量与煤气量特性曲线控制中间包升温过程。
Before pouring in the tundish, it is necessary to heat the tundish to 1150 ° C according to the temperature rising curve. Traditional tundish baking device with automatic ignition, flame monitoring, gas pipeline testing, nitrogen purge function, the need to use thermocouple temperature measurement, material loss, increased costs, only about a week for each galvanic couple. If you meet the process requirements, in the package baking process, not time and temperature, and the use of the process of baking, will save a lot of cost. According to the characteristic curve of air volume and gas volume, the temperature rise process of the tundish can be directly controlled by the air volume and gas volume characteristic curve without considering other factors.
